plz give me answer plzzzzzzzz plz give me answer carefully​

Answer 1

1. Distinguish between Speed and Velocity -

Answer:

Speed -

• Speed is the Distance Travelled by an Object per Unit Time. It does not have any Direction.
• Speed is a Scalar Quantity.
• The Speed of an Object can never be Negative. At the Most, it can become 0.

Velocity -

• Velocity is the Displacement of an Object in a Given Interval of Time. It has a Direction.
• Velocity is a Vector Quantity.
• The Velocity of an Object can be Negative, Positive or Zero.

2. Under what condition(s) is the magnitude of Average velocity of an Object equal to its Average Speed?

Answer:

The Magnitude of Average Velocity of an Object is Equal to its Average Speed, only when the Object is moving in a Straight Line.

Answer 2

Explanation:

1) Speed is the rate at which an object covers distance in a particular time. Velocity is the displacement traveled by a body per unit time. It is a vector quantity.

2) Average velocity would be equal to average speed when the total distance travelled equals the net displacement of a particle. This happens when a particle moves along a straight line in a fixed direction.
